Structure of carton sealing sticker and cutter

ABSTRACT

A carton sealing tape sticker and cutter mainly consisting of an auxiliary roller pivoted between the main roller and the word printing device. The word printing device has the functions of tape direction and guiding. The auxiliary roller not only aids the main roller in pressing the pasted tape flat but also conducts the turning movement when the structure turns from one side of the caton to another side. Then, the main roller continues the turning accordingly to maintain the turning operations smoothly. When the tape is pulled out for use, the tape drives the word roller of the transfer printing device into rotation. The word roller&#39;s surface has protruded words or figures, which maintains proper contact with the color printing roller during rotation and also makes the printing material stored in the color printing roller attach on the protruded words or figures and print on the back side (the glue-containing side) of the rotated blank transparent tape which is then immediately pasted on the place the user wishes. In this way, the printed words or figures will never be eliminated and the carton sealing transparent tape performs the functions of advertisement and sealing at the same time.

FIELD OF THE INVENTION

The present invention relates to a new structure for a manualcarton-sealing tape sticker and cutter, particularly to the structurethat during the process of sealing carton, the back (the glue-containingside) of the used blank transparent tape can be printed with set wordsand can also turn 90° to continually paste the tape to another side ofthe carton.

BACKGROUND OF THE INVENTION

Except for heavy products, various finished products delivered by allmanufacturing factories are often packed in corrugated cartons. Some ofthe tapes used to seal these cartons are transparent blank tapes.Regrettably these tapes only allow the gluing action without providingany other functions

The conventional carton sealing tape sticker and cutters can onlyperform straight line sticking, but to seal the carton over its entiresurface often requires a 90° turn from the top of the carton to itssides in extension or even to its bottom. This is a very difficultoperation because only a main roller is provided. Besides, it is laborand time consuming and an undesirable quality is usually achieved.

OBJECTS OF THE INVENTION

The primary object of the present invention is to solve the defectsfound in the aforesaid conventional carton-sealing tape stickers andcutters by providing a new structure for the carton-sealing tape stickerand cutter. According to this new structure, an automatic word printingdevice is installed on the direction-guiding roller to automaticallyprint the set words or figures on the back of the tape which passesthrough the device. Then this tape is immediately stuck on the opening,so the printed words or figures on the front side of the tape cannot beeliminated and cannot easily be imitated by other people. In this way,the carton-sealing transparent blank tape performs both advertisementand sealing functions.

A further object of this invention lies in that an auxiliary roller isadded between the main roller and the word printing device. Duringturning, this auxiliary roller can act mutually with the main roller toeasily turn from one side to another side of the carton. Thereby itsaves packing time and also enhances the quality.

SUMMARY OF THE INVENTION

The structure of carton-sealing tape sticker and cutter of the presentinvention mainly comprises the body, a tape sleeve ring, a main roller,an auxiliary roller, a word printing device and a cut-off device. Anauxiliary roller with a diameter smaller than the main roller diameteris installed between the main roller and the word printing device tomake the tape turn easily and continually seal and stick to another sideof the carton while sealing the carton. When the transparent blank tapeis pulled out for use and passes through the word printing device, theword printing device can automatically print the engraved words orfigures of the word roller on the back (the glue-containing side) of thetape. The word roller is installed at position of the direction-guidingroller shaft of the conventional tape sticker and cutter. A colorprinting roller device is installed between the two side boards of thebody at the position adjacent to the direction-guiding roller shaftdevice in contact with the word roller. When using the tape, the outputtape drives the word roller and the color printing roller in rotation atthe same time. Meanwhile, the printing material of the color printingroller attaches to the protruded words of the word roller. Immediately,the words are printed on the back of the blank transparent tape and thetape is stuck and seals the opening of the carton.

Body 1 has two side boards, the left sideboard 7 being short and only provided on the front of body 1, and theright side board 8 being long. The front of right side board 8 and theleft side board 7 are both pivoted on the main roller 3, auxiliaryroller 4, word printing device 5 and also coupled with the blade 33 ofthe cut-off device 6. The rear part of the left side board 8 is singlyjoined to the tape sleeve ring 2. The front of the top plane of griphandle 10 has a bulging form to mesh the concave depression in theuser's palm when he grasps the handle and makes his palm closely contactthe handle. The tape sleeve ring 2 has a hollow cylindrical shape whoseoutside diameter is adapted to the inner diameter of the tape sleevering 11, and, as described above, is singly joined to the rear part ofthe right side board 8 to sleeve on the type roll. Besides, asemi-circular hole 12 is shown on the right side board 8 covered by thetape sleeve ring 2. When the user grips the grip handle 10, his middlefinger, ring finger and small finger can be inserted into semi-circularhole 12 for easy holding and operation. Main roller 3 and auxiliaryroller 4 are both of cylindrical forms, and their pivot point can be amovable shaft or a fixed shaft. The outside diameter of main roller 3,however, is bigger than that of auxiliary roller 4. Main roller 3 rollsand presses the tape to closely contact the adhesive face; auxiliaryroller 4 aids the main roller 3 to turn the adhesive face 90° forcontinually pasting the tape on contiguous sides of the carton.

As shown in FIGS. 2, 3 and 4, the word printing device 5 of the presentinvention is also pivoted between the two side boards 7 and 8, and ispositioned behind the auxiliary roller 4. It has the function of guidingthe tape direction and automatically printing words on the back of thetape. The printing device 5 is composed of the word roller device 13 andthe color printing roller device 14. The word roller device 13 issleeved wherein the word roller 16 is sleeved on the pivot rod 15, andthe completed roller device 13 is inserted and positioned into the slotholes 17 on the two side boards 7 and 8 of the body 1. A through hole 18is respectively installed on device 13, whose neighboring perimeter isprovided with three or several through catch holes 19 to join the colorprinting roller device 14 which is composed of cabinet 20, pivot rod 21,color printing roller 22 and tension spring 23. Cabinet 20 has an arcshape and each of its two ends, respectively, has an end wall 24. Acatch pin 25 is provided on the outer rim of the end wall 24 andcorresponds to the catch holes 19 on the two side boards 7 and 8 fortheir mutual mesh to make the color printing roller device 14 fixed at aposition adjacent to the word roller device 13. A pivot hole 26 having aslightly long opening is installed at the center of the cabinet 20. Apositioning protruded pin 27 of the extension spring 23 is installed onthe cabinet 20 to mesh with the extension spring 23 which in turn forcesthe pivot rod 21 to move outward towards the opening in cabinet 20,thereby making the color printing roller 22 maintain proper contact withhe word roller 16. A journal 28 having a small diameter is respectivelyprovided on each of the two ends of pivot rod 21, and engages with thepivot hole 26 on the roller ends of cabinet 20 respectively after thepivot rod 21 is inserted into the color printing roller 22. Journal 28also goes through and protrudes some distance over the two ends ofcabinet 20, and the extensional force of extension spring 23 drives thejournal 28 moving outward along the long pivotal hole 26 to make thecolor printing roller 22 that is sleeved on the pivot rod 21 properlycontact the word roller 16. The color printing roller 22 is made ofstrong absorbent fibers or fabrics which can absorb a large amount ofprinting material.

As shown in FIGS. 3, 5 and 6, the aforesaid word roller 16 is made of aproper material suitable for being engraved with bulging words or convexfigures. The center of word roller 16 defines a pivotal hole 29 tosleeve and join the pivot rod 15. The rim of word roller 16 can be aunitary surface (as shown in FIG. 6) or have two or more parallel slots30 which may be the parallel central lines or have proper angle (asshown in FIG. 5) to separate the roller's surface into two or moreconvex arc portions 31 with set protruding words or FIGS. 32 thereonrespectively. Therefore, after the convex arc portions are inked withthe printing color, the convex arc portions can print the set words orfigures on the back (the glue-containing side) of the blank transparenttape.

As shown in FIGS. 2 and 7, the cut-off device 6 of the present inventionis installed in the slide slot 34 under the rim of the top board 9 andbetween main roller 3 and the auxiliary roller 4. The cut-off device 6is composed of the blade 33, slide slot 34, pull-extension spring 35,top block 36 and drive slide board 37. The edge on front rim of theblade 33 is of a oblique form, two holes are provided on a rear end ofthe blade 33 to firmly hook up the hook of the pull-extension spring 35.The width of the blade 33 is suited to the distance between the sideslots 34 on two side boards 7 and 8 and the blade 33 is set therein andmoves back and forth. The other end of the spring 35 is hooked on thepin 39 installed on the two side boards 7 and 8 under the drive slideboard 37. In this way, the spring 35 performs the function of pullingthe blade 33 backward to be stopped by the top block 36. The top blockis pivoted in the inner rims between two side boards 7 and 8 and one endof them tops the rear end of the blade 33 and its other end is sleevedin the catch slot 40 installed at two sides of the drive slide board 37.The drive slide boards 37 are sleeved on the bottom of the top board 9by the slide slot 41 and rivet 42.

The use and action of the present invention is first to make thesuitable transparent blank tape roll 43 be sleeved on the tape sleevering 2, and make the tape head 44 be pulled out and through and over theplace between the auxiliary roller 4 and word roller device 13. Then,the rear end of the tape head 44 is pasted on the word roller 16 and thetape head 44 extends some amount past the auxiliary roller 4 (as shownin FIG. 2 ). This is done in preparation of use, before use iscompleted. While using the device, the user grasps the grip handle 10 ofthe rear part of the body 1 with his right hand, and makes the mainroller 3 face the beginning position of the carton where the userintends to paste. Then, the extended tape head 44 is pressed on thebeginning position by the auxiliary roller 4, and the main roller 3presses tightly against the pasting surface. Tape is pulled outimmediately, and the words or figures which are set on the word roller16 are printed on its back (the glue-containing side) when the tapepasses over the word roller 16, the printing tape is immediately andflatly pasted on the rolling surface of the main roller 3. When the userwants the tape to turn 90° to continually paste another side of thecarton (as shown in FIG. 8), he may first cause the auxiliary roller 4turn to another side and then immediately cause the main roller 3 toturn and continue to paste. At the final time to cut off the tape, theuser needs only to insert his forefinger into the rectangular hole onthe top board 9 to mesh the snap hole 45 on the drive slide board 37 formoving backward. The drive slide board 37 is pushed backward and thecatch slots 40 on the two sides of the top board 9 drive the block 36 topush out the blade 33 to cut off the tape. The user's forefingerreleases and gets off the snap hole 45, the pull-extension spring 35contracts to take the blade 33 back, and meanwhile, the rear end of theblade 33 pushes the top block 36 which in turn pushes the drive slideboard back to its original position.
